What are tropic movements in plants?

• Tropic movements are the seasonal changes in plant colors.

• Tropic movements refer to the way plants absorb water from the soil.

• Tropic movements are directional growth responses of plants to environmental stimuli.

• Tropic movements are the process of photosynthesis in plants.

Define positive tropism.

• Positive tropism is the process of an organism remaining stationary in response to a stimulus.

• Positive tropism is the growth or movement of an organism towards a stimulus.

• Positive tropism refers to the movement of an organism in a random direction.

• Positive tropism is the growth away from a stimulus.

What is negative tropism?

• Negative tropism is the process of photosynthesis in plants.

• Negative tropism is the movement towards a stimulus.

• Negative tropism refers to the growth of an organism in response to light.

• Negative tropism is the movement or growth of an organism away from a stimulus.

What is phototropism?

• Phototropism is the growth of plants towards light.

• Phototropism refers to the wilting of plants in the dark.

• Phototropism is the process of plants growing away from light.

• Phototropism is the ability of plants to absorb water from the soil.

Give an example of positive phototropism.

• A tree growing straight up without bending.

• A flower opening at night.

• A plant wilting in the shade.

• A sunflower bending towards the sun.

What does negative phototropism refer to?

• No growth response to light sources.

• Growth of a plant in a circular pattern.

• Growth of a plant away from light sources.

• Growth of a plant towards light sources.

Explain geotropism.

• Geotropism is the directional growth of plants in response to gravity.

• Geotropism refers to the movement of animals in response to gravity.

• Geotropism is the growth of plants towards sunlight.

• Geotropism is the process of plants absorbing water from the soil.

What is positive geotropism?

• Positive geotropism is the growth of plant roots towards the gravitational pull.

• Positive geotropism is the response of plants to light direction.

• Positive geotropism refers to the upward growth of plant stems.

• Positive geotropism is the growth of plant leaves away from gravity.

What does negative geotropism mean?

• Growth of plant parts towards gravity

• Growth of roots in all directions

• Negative geotropism is the growth of plant parts away from gravity.

• Absence of growth in plants

What is hydrotropism?

• Hydrotropism refers to the movement of water in the soil.

• Hydrotropism is the growth of plant leaves towards sunlight.

• Hydrotropism is the process of plants absorbing nutrients from the air.

• Hydrotropism is the growth of plant roots towards moisture.
